- Occurrence of Dose Limiting Toxicities (DLTs) [ Time Frame: Up to 28 days ]To evaluate the number of subjects who experienced DLTs during the dose escalation phase
- Treatment Emergent Adverse Events (TEAEs) and Treatment-related AEs by Severity [ Time Frame: Up to 30 days after last treatment ]To evaluate the number of TEAEs and treatment-related AEs by severity for all dose groups/cohorts according to the National Cancer Institute Common Terminology Criteria for Adverse Events Version 5.0 (NCI CTCAE v5.0)
- Best Overall Response (BOR) [ Time Frame: Through study completion, an expected average of 1 year ]To evaluate the best overall response from study treatment according to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) and Immune Response Evaluation Criteria in Solid Tumors (iRECIST) criteria per Investigator assessment
- Duration Of Response (DOR) [ Time Frame: Through study completion, an expected average of 1 year ]To evaluate the duration of response from study treatment according to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) and Immune Response Evaluation Criteria in Solid Tumors (iRECIST) criteria per Investigator assessment
- Exploration of KD033 (SAR445710) Pharmacokinetic (PK) Profile - AUC [ Time Frame: Through study completion, an expected average of 1 year ]Area under the concentration versus time curve (AUC)
- Exploration of KD033 (SAR445710) Pharmacokinetic (PK) Profile - Cmax [ Time Frame: Through study completion, an expected average of 1 year ]Maximum plasma concentration observed (Cmax)

Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Histologically or cytologically confirmed/documented advanced and/or metastatic solid tumor with at least one tumor lesion of location accessible to biopsy per clinical judgement of treating physician.
- Subjects must be willing to provide a tumor biopsy at the following time points: Pre-treatment and at Cycle 4, Day 1. All other study eligibility criteria must be met before any biopsy sample is obtained.
- Measurable disease at baseline per RECIST v1.1 guidelines.
- Life expectancy of at least 3 months.

- Adequate organ and bone marrow functions.
- All toxicities related to prior radiotherapy, chemotherapy, or surgical procedure must have recovered to baseline or Grade ≤ 1 based on NCI-CTCAE v5.0 except alopecia (any grade), Grade 2 peripheral neuropathy and adverse events that are clinically non-significant or stable on supportive care.
- All subjects, male and female, who are not surgically sterilized or postmenopausal must agree to use 'highly effective methods of contraception' during the study and for at least 60 days after the last dose of KD033 (SAR445710).
- Women of childbearing potential must have a negative pregnancy test within 7 days prior to KD033 (SAR445710) treatment.
- Ability to understand the purpose of the study, provide signed and dated informed consent from the subject/legal representative prior to performing any protocol-related procedures and able to comply with the study procedures and any locally required authorization.
Exclusion Criteria:
- Use of immunotherapy, biological therapy, cytokine therapy < 21 days prior to the first dose of study drug.
- Use of immunomodulating agents < 21 days prior to the first dose of study drug.
- Use of chemotherapy and approved tyrosine kinase inhibitor (TKI) therapy < 14 days prior to the first dose of study drug.
- Anti PD-L1 or anti PD-1 therapy < 6 weeks prior to the first dose of study drug.
- Radiotherapy within 14 days before the start of trial treatment (prior diagnostic biopsy is permitted), with the exception of palliative radiation as described: patients assigned to radiotherapy require at least 1 additional lesion that can be safely irradiated while sparing the index lesion(s), and for which radiation at the limited, palliative doses contemplated would be considered medically appropriate; The lesion should be causing some signs or symptoms (e.g., tumor-related pain), for which radiation is indicated per the physician's standard clinical practice.
- Use of any investigational drug or have major surgery within 28 days before the start of trial treatment
- Ongoing or recent (within 2 years) evidence of significant autoimmune disease that required systemic immunosuppressive treatments.
- Systemic therapy with immunosuppressive agents including corticosteroids within 14 days before the start of trial treatment with the exception of corticosteroid replacement therapy for adrenal insufficiency
- Rapidly progressive disease which, in the opinion of Investigator, may predispose to inability to tolerate treatment or trial procedure.
- History or clinical evidence of central nervous system primary tumors or metastases including leptomeningeal metastases unless they have been previously treated, demonstrated no progression at least 1 months, are asymptomatic and have had no requirement for steroids or enzyme inducing anticonvulsants in the last 14 days before Screening - Subjects with suspected brain metastases at Screening should undergo a CT/MRI of the brain prior to study entry.
- Receipt of any organ transplantation including hematopoietic cell transplantation.
- Has a paraneoplastic syndrome of autoimmune nature.
- History of interstitial lung disease or severe obstructive pulmonary disease.
- Clinically significant cardiovascular/cerebrovascular disease.

- Vaccination with live vaccines while on trial is prohibited. Administration of inactivated vaccines like inactivated influenza vaccines is allowed. COVID-19 vaccines are approved to be administered prior to KD033 (SAR445710) administration and during the treatment phase, however, it is preferred to not vaccinate during the 28-day DLT period.
Note: Other protocol-defined exclusion criteria could apply.
